Ubuntu is pretty stupid with one thing… if you want more recent software, you are supposed to upgrade your entire distro. Which basically means that you're mostly not using a long term support (LTS) version. Which I wouldn't recommend.
(While, if you talk to devs about your problem, they always bill we like: First, use the latest version and see if the issue has gone already.)
Ubuntu Studio can't change that thing in Ubuntu. It's something all Ubuntu-based distros suffer from.
It's not a big deal if, say, your KDE is outdated. But in the audio/video world on Linux, things are still moving fast, like ffmpeg supporting new file formats (and you using a PPA to get a recent ffmpeg), or, say… Darktable supporting a recent camera RAW format… and so on.
So I just installed #Darktable 5.2 from a #PPA on my #UbuntuStudio in order to see if it produces TIFF files that actually are technically correct enough for #NeatImage to understand them.
Result is that now #Gimp does not launch Darktable anymore when I try to open a RAW file. Because this is apparently Ubuntu(Studio) magic that I lost.
“Luckily” also Darktable 5.2 cannot create proper 32bit float TIFF files, it seems to do perfect EXR files, but NeatImage can't read that. So I can roll back the entire maneuver…
