9.1.2 6463-88 55r625 Default parameters apart from 0 sharpening, Dolby dark, natural cinema, local contrast medium, brightness normal.
The built in roku apps of Netflix and Amazon Prime (only tested with Dolby Vision shows) apply image processing that makes the image appear sharper / more detailed. It looks like selective edge enhancement and it cannot be turned off. Tested at the max bit rate, double checked with the debug overlay.
Furthermore, testing with a 4k resolution chart for aliasing, sharpening seems to be applied at 20 unlike their claim that 20 is the zero point *edit, I changed something else and now 20 seems to be a 0, I really hope TCL can step in and explain what happens between 0 and 20. Also, If you pull the test patterns show in Netflix and use their regular chart, it shows some sort of artifact where the middle 1px bar is drawn through the center photograph. I don't know if that is a gamma or chrome sharpening diagnostic, but it is not visible on the Vizio. The bar also has a color cast on the r625. Unlike above enhancement, this is with the built in app and the fire stick 4k both, tested to be streaming at the max nitrate.
