Compression fitting?

Can anyone tell me, by this picture, if this is a compression type valve? I’m needing to replace this toilet and want to replace the valve and supply also.

Loos like it's not, and there are 1/4 turns available.

Thanks, I’m concerned about the limited space to install a new valve. Good thing is there plenty of working space under this house (cabin).

What am I missing?

It appears to be a threaded fitting, so just unscrew, by holding the fitting behind the valve, and turning the valve.

Maybe? I’m hoping it’s that easy! I don’t want to open a can of worms lol.

If there is a second floor above this, open all the faucets.
Then, when you unscrew this valve, expect a half gallon or so of water to eventually come out of the stub. The last cup takes much longer than the first cup.
The drywall will get soaked.
