Maps on 1030 vs. 1050?

I was using Hammerhead Karoo for a while, then dropped it and bought Garmin 1030 plus. 
I much prefer the responsiveness and battery life of the Garmin, but I can't see much on the screen  whether in the daylight of high contrast mode - advanced middle age and glasses and such. 
I went back to Hammerhead 2, and I can see the maps much better. 

Have the maps on Garmin 1050 changed? 
Are they more visible?
Can colors and graphics be adjusted better than on the 1030?
