I'm not sure I'm going to say this right, so let me meander for a bit:
There is no 'chrome' in LDraw. There is a need to have an agreed-upon
color-code for chrome, so that people and programs can recognize
chrome parts when they run into them. There's no way to add a new,
solid color to LDraw. So the L-CAD group has declared one of the
dithered colors to be 'chrome'.
It seems more likely that users would want chrome rather than a
non-LEGO extra-light gray. So practicality should win over
consistency, and the conversion tool should render color #383 as a
chrome texture.
If you want a light-gray that won't be rendered as chrome, try
15*16 + 7 + 256 = 503
