No, it was only 2 of the 3 battlecruisers lost at Jutland that were doomed by unsafe ammo handling practices. Invincible was in the 3rd Battlecruiser Squadron, which had been detached to the Grand Fleet and thus participated in the Grand Fleet's regular gunnery exercises at Scapa Flow. As such, her crew didn't try to make up for inability to practice long-range gunnery via the "throw enough shit at the wall" tactic the way Beatty's fleet did, and instead actually used the flash doors on their magazines. (Unlike the 1st and 2nd Battlecruiser Squadrons under Beatty, Invincible and her sisters also showed excellent gunnery when they arrived at Jutland. It's quite unfortunate that all 3 battlecruiser squadrons weren't at least rotated through Scapa flow periodically, so that everybody would get at least some proper gunnery training of the sort that wasn't possible at Rosyth.) Invincible was doomed because she was fighting above her weight class, and her 6" armor was simply insufficient to stop Lützow's 12" AP shells.

It's extremely unlikely that Von Spee could've made it back to Germany. At most, he might've been able to sacrifice Scharnhorst and Gneisenau by aggressively charging into Stanley Harbour while the British ships were still building up steam, allowing his light cruisers to flee. That would've brought him into close enough range that his guns would be an actual threat to Invincible and Inflexible. And more importantly, once his ships were inevitably sunk by the superior British force, their wrecks would likely block the Narrows and keep the British battlecruisers and armoured cruisers from leaving until the wrecks were cleared. this would likely give his own light cruisers enough time to escape. And the light cruisers might have been small and fast enough to slip through the British blockade once they reached the North Sea. Scharnhorst and Gneisenau would not have been.

@WalterReimer Ah yes, HMS Exploder and HMS Excruciater.

For starters, I imagine the Renowns (laid down a month and a half after the Falklands) would've immediately had their construction delayed long enough to do away with the bizarre design decision of a 6" armor belt. At an absolute minimum, they'd revert to a 9" belt like the Lions and Tiger already used. ie what they historically were given in 1920s refits. Or possibly even the Design Y battlecruiser (the "Super Tiger", with 11" belt and 4x2 15" guns) would've been built instead. Possibly the funding that went to 2 Renowns and 3 Courageouses historically would've gone to 4 Super Tigers. Or just 4 up-armored Renowns. Aside from Indefatigable being in immediate need of replacement, there'd be a perception that her sister ships are inadequately armored, while Germany's own battlecruiser fleet would still need to be countered. Adding 4 instead of 2 15" armed battlecruisers would allow Australia and New Zealand can be sent to safer duties than directly confronting their German counterparts, while still directly upgrading the fleet's strength. Though of course Jutland would happen before any of the new ships would be complete, so this plan wouldn't have a chance to be put into practice. When it comes time for Jutland, the 2nd and 3rd Battlecruiser Squadrons would probably have been rearranged to account for Indefatigable's loss. Most likely it would be the now under-strength 3rd (consisting only of Australia and New Zealand) that gets detached to the Home Fleet, leaving the 2nd Battlecruiser Squadron (the 3 Invincibles) at the tail of Beatty's battle line. No way to know whether the collision between Australia and New Zealand would still happen when they're up at Scapa Flow, but it's possible that New Zealand will be the only battlecruiser attached to the Grand Fleet at Jutland. This would actually be an upgrade to Beatty's force, though whether he'd gain any advantage out of this is questionable, since it's Beatty.
