D65 white point for all content?

[yougottaguys]

Recently got my first OLED (not setup yet) and wanted to clarify something beforehand.

I often see reviewers advocating for calibrating a TV to match the D65 white point. However I recently watched a Youtube video about this and I saw two comments that made me a bit concerned -

I understand that D65 is an industry mastering standard but how widely does this span across time and the different industries? I'd like to calibrate my display to be as accurate as possible but I worry that content without an industry mastering standard i.e video games will (with certain games) appear overly warm, dim and yellow.

I assume this won't apply to the vast majority of films and TV shows if D65 has been a standard during the entirety of the digital era. As in recent films/tv shot digitally and older films/tv shot on film then scanned & transferred digitally for DVD/Blu/4K would both be mastered to D65. Is that correct?

My tastes are mostly pre-2000s movies, pre-2010s animation (western cartoons & anime) and pre-2010s games.
Although I do watch more recent movies, TV shows, anime and play modern games on the odd occasion.

I understand that calibrating to the D65 white point would make real life footage appear more natural and would in general cause less eye strain. But judging from those comments it sounds like not all content meets the D65 standard or benefits from it.

If so would I be able to have custom calibrated presets on a Sony OLED? As in one preset calibrated to D65 (or I may just select the "custom" picture setting) and another which suits non-D65 content more which would be perhaps somewhere in the middle - not as unnaturally blue as default but not as yellow as D65.
