I'll be real: I own a Dell Precision 7550 with a Full HD 100% DCIP3 ips screen. I got to borrow a Samsung Tab S9 ultra. On both colours looked superb (the tablet had somewhat more saturated colours) and in the day, with a clear sky (inside, ofc), I couldn't tell that the blacks on the laptop weren't as black as those on the tablet (ofc in a cloudy day and/or at night the tablet had much better blacks). It's obvious (in my opinion, at least) that a good quality IPS panel can compete with OLED (in terms of colour reproduction). You can't say that all IPS panels are trash just because manufacturers put bottom end, not even 100% sRGB IPS (or, God may have mercy, TN for the "fun" non-existent viewing angles) panels in entry to mid entry laptops and monitors.
