I didn't see any difference between DRI and no-DRI mode, they all got the following  
result:
read out pixels:
(48, 49) = [0.000000, 0.000000, 0.250980]
(49, 49) = [0.000000, 0.000000, 0.250980]
(50, 49) = [0.000000, 0.000000, 0.250980]
(51, 49) = [0.000000, 0.000000, 0.250980]
(48, 50) = [0.000000, 0.000000, 0.501961]
(49, 50) = [0.000000, 0.000000, 0.501961]
(50, 50) = [0.000000, 0.000000, 0.501961]
(51, 50) = [0.000000, 0.000000, 0.501961]
(48, 51) = [0.000000, 0.000000, 0.749020]
(49, 51) = [0.000000, 0.000000, 0.749020]
(50, 51) = [0.000000, 0.000000, 0.749020]
(51, 51) = [0.000000, 0.000000, 0.749020]

Mass version move, cvs -> git
