Only if the CRT is still of sufficient age. All CRTs today are now old and over-used. The CR tubes inside a CRT lose their performance as time goes on which results in output quality not being consistent over the years due to the way a CRT works. Fire up an 80s or 90s TV or CRT monitor today and you will see all the tells of a screen that is fatigued, focus issues, colour issues, contrast issues...
If it's had very little use then sure it will be good still, but a modern OLED will walk over it in all areas other than motion smoothness. I don't include scaling in that because many OLED screens now have excellent scalers and CRTs are inherently blurry, since modern games are developed for flat panels, they will just not look sharp enough on a CRT so the technology really is antiqued by the nature of what it is so really this whole debate is pointless because a CRT has no place in modern gaming as the engines are not designed for them.
An LCD panel such as IPS does not have this issue as long as it's using an LED backlight instead of early LCDs that had CCFL backlights. OLED panels don't have this issue either though it can be argued individual OLED pixels can degrade, but that has yet to manifest as loss of colour accuracy over time, just screen burn. OLED is just better at colour reproduction, which is why today in 2024 we have factory calibrated OLEDs that are near enough industry grade colour accurate for D65 SRGB use out of the box. This hasn't been the case before with displays, I worked in a photo studio editing for the lab where we only used the latest Eizo CRTs and they needed to be calibration checked and adjusted every month because of the volume of use they had at least 5 days a week for at leats 7 hours each day.
Fact of the matter is that tubes age, and back when CRTs were mainstream, they were used a lot.
OLED is the immediate future and we are seeing the benefits right now, there are a few things that will be ironed out as the generations evolve like VRR flicker and burn-in, but other than that we are now seeing 480Hz panels with 1440p resolution, and 1000Hz won't be far away, as many are calling 1000Hz OLED the holy grail to get true CRT motion clarity with all the advantages of OLED as mentioned
Actually Micro LED is the long future, but currently they are super expensive and a niche in the professional world. That will change over time though.
Currently Samsung Micro LED displays can be bought, smallest size if 89" and will cost a mere $109,000
Feel the breathtaking scale of the Samsung Micro LED’s cutting-edge display, sound and high-end big screen with the ultimate level of realism.
