I think the Irish Met have named most of the named storms we've seen so far this winter, they have lower thresholds for wind speeds/warnings. I expect if the Irish Met hadn't have named Eleanor then the UK Met would've given they issued an amber warning for gusts in excess of 80 to 90mph, and you could argue they would've issued a red warning if the storm had impacted the UK during the day at a busier time.
Named storm or not, any warning be it yellow amber or red is issued to make people aware of the potential for disruption to their daily lives, obviously the higher up the scale more serious impacts are expected which may prevent us going about our day to day lives, and pose serious risks.
