No, I don't think so.

    3784704 - 3670016 = 114,688
    114,688 / 1024 = 112
    3670016 / 1024 / 32 = 112
    3784704 / 3670016 = 1.03125

    270336 - 262144 = 8,192
    8,192 / 1024 = 8
    262144 / 1024 / 32 = 8
    270336 / 262144 = 1.03125

    29196288 - 28311552 = 884,736
    884,736 / 1024 = 864
    28311552 / 1024 / 32 = 864
    29196288 / 28311552 = 1.03125

    1 / (1.03125 - 1) = 32

The image is always the same factor bigger than the device size, 1/32th,
suggesting a consistent overhead in the data format.
