Yes, this is sadly yet another blue regimental flag - but this time we have a regiment that had a very busy Seven Years War. It was at the capture of Guadeloupe in 1759 then in Germany at the battle of Warburg 1760, with its grenadiers at Klostercamp the same year. In 1761 it was at Vellinghausen plus numerous smaller engagements. In 1762 it was at Wlihelmstahl. See the Kronoskaf page here: https://www.kronoskaf.com/syw/index.php?title=8th_Foot for much more detail and an account of its earlier history, plus uniform details.
The motto Nec Aspera Terrent is often depicted on the regimental colours for this period but, as Milne in his book Standards and Colours of the Army 1661-1881 explains, it was not officially authorised until 1840 when it first appeared on the regimental colours.
