I don't think it's acceptable to precede a D with an L or to have more that one D in a number. However, putting that aside and following the basic addition and subtraction rules for Roman numerals, I would say it is a sloppy way of expressing 1055.
D = 500
"LD = 500 - 50 = 450"
C = 100
V = 5
500 + 450 + 100 + 5 = 1055
The proper way to express 1055 in Roman numerals is MLV.
