The ones I used look like this: http://www.carpartslights.com/images/t10-5%20smd.jpg
Because they have 5 LED's, they should distribute light fairly similarly to a regular bulb. I think they're just a lot brighter and therefore create the hotspots. Attached is a pic (garage lights off, no flash, dash lights on). You can see the hot spots at the top left and top right. I'm quite ok with it, particularly since 0-140KM/h is well lit (I'm not generally riding past 140...) and the tach is lit in the important ranges as well...
Before the LED's, the 160-220 range on the speedo was about the brightness of the entire speedo and tach.
The camera really doesn't pick up the LCD - it's much, much more readable than the picture show.
