IWDA, SWRD and LCWD track the same index - MSCI World, but VHVE tracks a different index - FTSE Developed World. There are subtle differences between the 2 indices, eg. included countries (S.Korea, Poland) and the number of companies (85% vs 90% of the universe). You should not compare the price/performance of VHVE directly with that of the other 3 ETFs, as they will definitely be a bit different.
I think the price difference is mostly attributed to the low volume of SWRD and LCWD.
The chart below compares IWDA, SWRD, LCWD for the last 2 weeks, in hourly interval.
If you see a flat line, it means there was no trade volume for those hours. LCWD has very low volume, sometimes not a single trade in a day. SWRD is better, but you can still see stretches of a few hours without any volume. IWDA has the highest volume, and price moves up and down frequently.
The LSE closes at 4:30pm UK time. When you look at the closing price of these ETFs, the last done price might occur at different times of the day. For example, IWDA at 4:30pm, SWRD at 3:30pm, and LCWD at 1:00pm. The index can move a lot within a single day. So, the price/performance difference you are seeing is likely due to the previous trade (of the start day) and last trade (of the end day) occurring at different times. 0.08% is too small to be reflected in the price, compared to the movements of the index. It is not meaningful to compare the performance of the 3 ETFs for the last 1 year. More meaningful to compare performance of 10 years and above, as the expected TER saving is more significant.
You may want to take some hints from SPY/VOO/IVV:

Do note that all 3 SPY/VOO/IVV are much larger than IWDA. They probably don't have an issue with spread. Ideally, the spread of SWRD and LCWD should be quantified in order to know whether you really save money.
