Code:

#itemDetailPage .detailImageContainer .card.portraitCard img,
#itemDetailPage .detailImageContainer .card.portraitCard .cardImageContainer {
    object-fit: contain !important;
    width: 100% !important;
    height: 100% !important;
    background-size: contain !important;
    background-position: center !important;
}

#itemDetailPage .detailImageContainer .card.portraitCard .cardBox:not(.visualCardBox) .cardPadder {
background-color: transparent;
}

Can you give that a try? It should force posters (portraitCard) to show their full width. Currently it crops the sides if they're not tall enough.
