About deep_channel_kernel's MaterialId

Hello RS Team
This new deep_channel_kernel with Material ID is great.
There is one issue and three question.
Issue: We have a strange black border (highly visible) coming in the Material ID channel. I tried many objects and many setups and its still present. Have a look at two attached images. It is more or less like appearing only on left side of intersections just like a shadow effect.
Q1: Is there a possibility we can choose the colors for Material ID our self? If yes, it would be great because, I would certainly like to try black and white colors (like MatteID) because, this will work exactly like alpha and I can use it in animation workflow.
Q2: The RGB values of this material ID colors are why only 50% bright? f.i. For red its R127, G0, B0.... and not R255, G0, B0.
Q3: This MaterialID output is great, and we can now easily crop the objects in photoshop, but how we do that in animation workflow? If I am not wrong, adobe after effects can read MaterialID/ObjectID channels only as .rfp file which also includes the RGB (render channel) into it. But, here we are generating the MaterialID channel as a .png file and I am not sure how I would utilize it in animation workflow. Any suggestion/help would be highly appreciated.
Thank you for attending my post.
Warm Regards
Jitendra.
