Which firmware are you running? How many books are on your device?
I've found older Tolino models much slower and less convenient to use than Kobos or Kindles. My Kobo Clara HD opens a book in 2-3 seconds max.
The Tolino Shine 3 and the Kobo Clara HD are the same device, as far as technical components are concerned. It might have the same speed.
Moreover, all screens look kind of grey if you don't turn the light on. It's hard to say which device has a lighter screen without a direct comparison. If I use my Kobo in bright daylight, I don't see a big difference with the light on or off. My boyfriend uses the Tolino Epos and Vision 4HD. Both have a kind of greenish comfort light, whereas my Kobo Clara has a nice orangey-yellow tint.
Is there a specific reason why you don't want to use the light?
