How about "<null>"? Makes it more obvious that it's actual null and not the string value "Null".

It better to make it in lowercase Null -> null.
<null>
I like any option except ?.
Although the string value still can be \<null\>.
In addition, we can use a different color for special values (only suitable for the console output)

I don't think it needs to be escaped. The XML serializer will automatically escape those to < >. Unless we don't want those escaped in XML, then maybe (null) instead.

Sorry, github markdown doesn't like <> characters and removes them if they are not escaped. I forgot to remove escaping when I added the single quotes.

Looks a little odd to me.

I think it looks good. But I guess that's just a matter of preference.
[Edit] But I think I like (null) better.

Null value is ok, but it is shown as unknown.
It's impossible to get Unknown value now, but I decided to add handling for this situation.
