Quick look for 'Land Rover wheels' in Nexa doesn't specify the wheel name & I only list two, both coming into use from the noughties so I don't know if it will be of any help but find a motor factor & check their paint swatches :
MNH 'Sparkle silver' (2004 on, contains a lot of 'Extra coarse aluminium' & some 'Coarse aluminium' so I'd expect it to be sparkly!) It's also listed for Rover in the 90's & Rover/Land Rover interchanged many colours usually with the same paint code but different names.
MBU 'Light silver' which shows for 2012 on so I don't think it'll be that one, although it contains even more 'Extra coarse aluminium' then MNH, but it also has other tints which I think may make it a bit darker.
