I think as to likenesses and costumes the artists below attempted to be fairly accurate, but even the Royal Collection's description of Hayter's Coronation scene painting tells of the liberties he took with the Abbey's architecture:

Unlike Charles Robert Leslie, however, who painted the same event (RCIN 406993), Hayter made no attempt to accurately record the shape or scale of the box in which the royal ladies sat. The canopy above this box and the temporary Gothic canopy above and behind it are fairly faithfully recorded by Leslie, but Hayter dispensed with them both and set the ladies in stalls under a high and imaginary Gothic canopy.

Below are details from the paintings of Hayter (left) and Leslie (right).
