Plasma has great contrast and a slightly wider gamut than a CRT. Neither one have particularly good gamuts unless you're comparing to sRGB. Many current screens can do much better.
"Professional CRTs
were manufactured to the SMPTE‐C standard gamut,
which closely matches the NTSC standard and slightly
exceeds the EBU (PAL/SECAM) standard. Any
limitations on the reproduction of certain color
shades were due to the maximum saturated levels of
red, green, and blue phosphor compounds used in
these monitors.
While coverage of SMPTE‐C and BT.709 color spaces
isn’t difficult to accomplish with a CRT, coverage of
new, extended color gamuts such as xvYCC and the
digital cinema P3 minimum standard gamut is
problematic for CRT phosphor imaging. At best, a
well‐designed CRT monitor could expect to cover
about 60% ‐ 70% of these wider spaces, which
typically push deeper into the green section of the
1931 CIE “tongue” color diagram."
This shows plasma as a little bit better than CRT, and again lists the limits of CRT gamut.

> slightly wider gamut than a CRT
Why is that? It's the same phosphors.
Do they usually use the same ones? I don't know, I just went based on some diagrams in a paper comparing techs.
I found something more useful though: https://www.panasonic.com/business/plasma/pdf/evaluationplas...

Lots of modern screens can do P3 and beyond. Some even get within a few percent of Rec.2020 https://upload.wikimedia.org/wikipedia/commons/thumb/b/b3/CI...
Maybe better phosphors are possible? Or you could put a quantum dot layer on top of CRT if you really wanted to? But I'm okay with dropping CRTs.
