Density is certainly changeable in water with temperature, but density isn’t exactly the same thing as compression.
TIL A waterjet cutter pressurizes the water to something like 90,000 psi and it gets about 14% more dense. I always thought those things just had the water highly pressurised, but not actually compressed.

I want to posit that because water isn’t compressible at forces we experience commonly, it doesn’t mean it isn’t compressible. For 99.999% of the water rules we concern ourselves with water should be considered incompressible, but there are exceptions to every rule
