This is exactly what I have been saying for a very long time now. There’s no “fishbowl” effect to be seen on most CRTs I grew up with in the 80’s to 2000’s. Maybe those who grew up or had CRTs from the 60’s to the 70’s might have had a different experience.
In any case the CRT Shader’s Curvature algorithm curves the screen on the X & Y axes to be displayed 2 dimensionally, whereas on a real CRT the curvature might have actually been on the Z axis so there’s a huge difference there.
Scanlines can be tweaked further. You can customize the spacing, shape e.t.c.
That’s probably why my “old” Aperture Grill presets still look so impactful when I load them even when compared to my current Slot Mask presets.
I did a lot of scanline tweaking on those.
Just be careful with the Fast Sharpen (or any other sharpening/blur filter) because sometimes they can negatively impact the outlines on pixel graphics in a way that actually reduces contrast so you can pay attention to if your black lines get less prominent when making sharpness adjustments.
