Some correction

No wide colour gamut
No Dolby vision

The major difference between them is still the screen type , both of the Samsung's are VA and thus better suited for dimmer room while the Panasonic IPS TV for brighter , bigger room .
The lack of support for Dolby Vision is fine for gaming for now , big brands has a built in dynamic tone mapping function nowadays .

But the absence of WCG can be problematic when TV try to map colors according to the HDR metadata .
Since the expression of wider color space and volume are both fundamental of HDR , you are better off completely turning off HDR on these TV .
