Can you say more around this ? What is inaccurate and not consistent ? TMDB has pretty good information when it comes to this metadata type. Regardless, even if it is indeed wrong we can just fix it as a community like any other metadata.
We can filter on studio so why not have it on the title screen ? IMO, studio should be extended in plex to include multiple studios as per feature request Allow For Multiple Studios Separated by Commas. This comment above is baffling to me.
Putting my tinfoil hat on, maybe the studios have requested plex to remove this as they don’t like to see their content filtered and called out on a plex server
