Do You Get True 256 Grayscale With A Modified SE/30?

[Paralel]

I've always been curious about this. Does the Micron Xceed grayscale modification for the SE/30 provide true 8-bit grayscale or is it less shades than that?

The two images I could find which is meant to show a 256 grayscale gradation has heavy banding, which I wouldn't expect to see if it could truly display 8-bit grayscale:

Of course, that could just be the monitor I'm viewing the image on (I don't know if this is a true 8-bit panel). Do you guys see the same banding in that image?

Does anyone have a grayscale modified SE/30 to test a full 8-bit grayscale gradation with?

For anyone that has one and wants to try it, here is a smooth 256 grayscale gradation:

If you're talking about the Control Panel sample, that's the way it's supposed to look in 8bit grayscale. It looks like that on 24bit capable systems.

I'm curious if it actually can display 256 shades of gray as well, or whether it is less than true 8-bit.

To confirm TRS80_HP's statement, the Monitors control panel *NEVER* shows a true full-8-bit grayscale gradient. Every single system I have ever used 256-grays on shows that same 8-shade gradient in the control panel.

Just as "Thousands" color mode shows a falsely-limited gradient. In reality, "Thousands" color mode would be perfectly capable of showing the same gradient as "Millions" color mode. The sample box is small enough that any mode above 256 cannot be fully shown, so they "dumb it down" to make it more obvious. I presume that 256-gray mode is similar - they just show a gradient to show it is more than 16 colors, not an actual full representation of the full palette.
