Yeah, but what was a 'neon yellow' or 'bright green' 1mm thick line on the 800 , became a 'dirty mustard' or 'sludge' 0.001mm thick line on the 1030. I once asked my wife which colour route she found easiest to see of the two- she replied... "what route?" :)
The 830 seems to have compromised with a 'fairly bright yellow/green' of 0.5mm thick (plus the rest of the map has better colour differentiation generally). This doesn't seem to have negatively impacted the battery, which was assumed to be the benefit of muting the colours so much on the 1030..
^ that's a bad example (it's someone else's pic designed to demonstrate something else) but you can see how the red, blue and black elements stand out a bit better - which is what my eyes really struggle with at night.
