No it’s not a simple binary decision. As I have proven on something that should only take 2GB of RAM was eating up all 192GB and causing insane swap (literally hundreds of GBs for the test).Seeing Red memory pressure during normal tasks is by definition an indication that you need more RAM. That's literally the point of it. Apple even calls this out in their own support documentation...
- Green memory pressure: Your computer is using all of its RAM efficiently.
- Yellow memory pressure: Your computer might eventually need more RAM.
- Red memory pressure: Your computer needs more RAM.

Use Activity Monitor on your Mac to see if memory is being used efficiently and if you need more memory (RAM).support.apple.com
I have faced many other issues with other apps too. Yes even browser tabs. I created a website that had memory leaks too.
That is why I talk to my clients for a good amount of time. Maybe they have seen something similar and the don’t need to waste money on more RAM if they can try an alternative app to see if it’s a bug or not. I don’t simply say “you see red memory pressure? Sorry get a new computer/more RAM.” I don’t agree with Apple’s docs here. It’s much more conversational approach. If I followed Apple’s documentation I wouldn’t be able to get a computer with more RAM. And the task doesn’t make sense. No 1080p video editing work needs more than 192GB.
